Abstract

La capsule de test est formée de pièces en matière plastique comprenant un corps cylindrique et un chapeau de bouchage, le fond du corps et du chapeau étant percé de petits orifices pour laiser passer le gaz à tester. Le débit de gaz qui peut passer dans la capsule est régulé par un ou deux éléments servant à obstruer le passage du gaz à une ou aux deux extrémités de la capsule. Les éléments peuvent être des billes sphériques qui sont appliquées contre des nervures prévues sur le fond du corps ou du chapeau. La précision du débit dépend de celle de la hauteur des nervures et du diamètre des billes. Utilisables notamment dans les alcootests.The test capsule is formed of plastic parts comprising a cylindrical body and a stopper cap, the bottom of the body and the cap being pierced with small orifices to allow the gas to be tested to pass. The flow of gas which can pass through the capsule is regulated by one or two elements serving to obstruct the passage of gas at one or both ends of the capsule. The elements can be spherical balls which are pressed against ribs provided on the bottom of the body or cap. The precision of the flow depends on the height of the ribs and the diameter of the balls. Usable in particular in breathalysers.
